Ruling tests HR’s reliance on policies over live evidence
A Christmas party, a naked swim allegation, and a Fair Work ruling that cost an employer $9,543 when its witnesses stayed home.
On 22 April 2026, Fair Work Commissioner Matheson ruled in Lester Box v Sirrom Co. Pty Limited. It is not a story about a rogue employee escaping consequences. It is about what happens when an employer cannot prove its own case.
Lester Box worked as a cleaner on a mining site for Sirrom Co. Pty Limited, an employer with 262 employees. On 15 November 2025, a social gathering was held at the site's barbecue and pool facilities, organised by his supervisor, Elizabeth. It involved music, drinking, and an after-dark swim that became the centre of a serious workplace dispute.
The employer alleged Box entered the site pool naked in front of colleagues, breaching site village rules, and that he consumed alcohol past the 10pm curfew. He was stood down on 18 November 2025, attended a show cause meeting on 24 November 2025, and dismissed two days later on a fortnightly wage of $3,181. He also alleged he was targeted due to his sexual orientation, but the Commission found no evidence of this.
What the employer had was not nothing. An HR Incident Report recorded that multiple witnesses independently identified Box as having entered the pool without clothing. His supervisor verbally confirmed this in an internal interview. Another witness, Ms Quintal, provided a document described as an “Affidavit” that appeared to have been signed in the presence of a Justice of the Peace.
Yet none of them appeared at the determinative conference. Elizabeth declined to provide a written statement, reportedly feeling responsible for organising the party, and did not testify. Ms Quintal's document existed, but she was not cross-examined. The Incident Report's author did not appear either. Box was the only person who gave direct evidence. The Commissioner noted reservations about his credibility but found the employer's case weaker still.
Separately, a witness statement filed by Box from a colleague, Ms Miller, alleged that a person called "Terry" asked Ms Quintal to say she was not at the party and had witnessed nothing, the request to be "kept between us." The Commissioner noted it seemed likely "Terry" was Terrence, the Catering Operations Manager and Reporting Officer named in the HR Incident Report, though no formal finding was made on this allegation.
Commissioner Matheson considered the respondent's evidentiary case to be "poor," ultimately concluding he was "unable to reach a firm conclusion, on the balance of probabilities that the alleged conduct occurred." No valid reason for dismissal was established, and unfair dismissal was upheld.
The Commission also found the 10pm rule the employer relied on was not a drinking curfew. The site rules addressed only excessive noise after 10pm. Other employees who remained in the pool area that night were not dismissed, which further weakened the case against Box.
On compensation, the Commission estimated Box would have remained employed for a further six months, placing the notional figure at $41,353. But Box had not looked for work since his dismissal in November 2025, telling the Commission he was waiting to see how the application resolved. The Commission found this unreasonable and reduced the award to $9,543, equivalent to six weeks' pay.
For HR leaders managing remote or FIFO workforces, the case offers pointed considerations. An investigation report, however thorough, cannot substitute for live testimony. A witness who will not testify leaves a gap the Commission will not fill. And when multiple employees engage in similar conduct, disciplining only one risks undermining the consistency any defensible process requires.
